Oh, WordPress plugin eh, that explains why the articles I submitted show up one day and not the next. That's how they do it, to get a grand total of 19,000 directories and publishers. One software shows 1,200 directories and the other shows 1,400 diretories, so the other 17,000 are webmasters who installed the plugin. This would also explain all the trackbacks.
Basically they mix and match, out of 19,000, lets say 20,000 for mathematical ease and you set it for default at 50 submissions, it would take 400 days to submit to all of those... There's a reason why they RECOMMEND a default of 50 and I don't think its got anything to do with Google...
